LAMP-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 247,715, dated September 27, 1881.

Application filed April 8, 1881.

light of a lamp, so as to avoid the danger of explosion; and to this end Iemploy the parts as will hereinafter be fully described.

To clearly convey my ideas, reference is had to the accompanying drawings, in which Figure 1 is a cross-section of a lamp-burner on line 00 a: of Fig. 4, showing the position of the parts of my extinguisher when the lamp is burning. Fig. 2 is a like section of the burner, showing the position of the parts of my extinguisher when the light is extinguished. Fig. 3 is a cross-section on line as w of Fig. 4. Fig. 4 is a top plan of a burner with part broken away, clearly showing the operating parts.

Ais the burner; A, its wick-tube. The wicktube Iprovide with myimproved extinguisher, consisting of the parts as follows: E is a false slide or sleeve, which I'construct so as to fit around the wick-tube loosely, and so as to be movable up and down on the same. The lower end of the sleeve is provided with two prongs, b, which rest upon the forked ends 0 of a lever, G, properly secured to the side of the burner at o, and having its fulcrum at 0 its other end, 0 passing out at the bottom of the burner to within reach of the operator.

A cap, D, is pivoted in the ears E, having slots 0, which receive the crank-shaped ends d of a pin, d, which secures the cap to the top of the sleeve, as shown in the drawings, and allows the cap to tilt over and back on the same.

Having thus fully described the construction and arrangement of my extinguisher, and the position of the parts being as shown in Fig. 1 when the lamp is burning, the operation of effective lamp-extinguisher.

(No model.)

the same is therefore as follows: By pressing down on the end 0 of the lever G the forked ends 0 of same are raised, and the sleeve B with it, as shown in Fig. 2. As the sleeve rises the cap D begins to turn over on its hinge by means of the crank ends, which move in the slots 6 of the guides E, which are stationary. As the sleeve rises until it fairlyclears the top of the wick, the cap moves on its hinge until it rests firmly down on and covers up the top of said sleeve, thus extinguishing the light.

As soon as the pressure on the lever is removed, the raised ends of same and the sleeve drop by their own gravity, and the cap is returned to its former position, leaving the wick free and ready for relighting. Now, further, should the lamp by any accident be upset, the parts work automatically. Being in an inverted position, the sleeve by its weight drops and the cover passes over the same and the light is out, thus preventing a possible explosion. Thus by my improvements is achieved a. simple, durable, automatic, and reliable as well as Having now fully described the construction and operation of my invention, what I claim is--- The sleeve B, with its prongs b resting on forked ends 0 of the lever O, the capD, pivoted in the ears E, having slots-e to receive the crank ends at, the cap being secured to the sleeve B, in combination with the wick-tube of a lamp-burner, and operated by pressure on the end 0 of the lever (J, and to form a lamp: extinguisher, as herein shown and described.

In testimony of said invention I havehereunto set my hand this the 4th day of April,

LOUIS VON 'FROBEN.
